Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

N-(1-butyl-3-cyano-4,5-diphenyl-1H-pyrrol-2-yl)isobutyramide (CAS 478032-68-7), molecular formula C25H27N3O and molecular weight 385.50 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-(1-butyl-3-cyano-4,5-diphenyl-1H-pyrrol-2-yl)isobutyramide (C25H27N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 385.50 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
